Description
Technical field
The present invention relates to a kind of largemouth bass feed, the largemouth bass expanded pellet diet of especially a kind of ultralow starch and its preparation side
Method.
Background technique
With the promotion of people's living standard, the demand to fresh and living aquatic products is increasing.Largemouth bass delicious meat, without flesh
Between thorn, price it is human-oriented, by the favor of the majority of consumers, there is huge consumption market.Pearl River Delta area cultivates largemouth bass tool
There is advantageous geography and climate advantage, also has apparent advantage in industrial chains such as seedling, feed, circulations.In recent years, with adding
The maturation of state perch whole process material formula and technique, the whole country in started largemouth bass cultivation upsurge.Since 2015, the whole nation added
State perch cultivation total amount rises to always 500,000 tons in 2018 by initial 300,000 tons, and it is expected that a few years from now on total output can
Up to 1,000,000 tons.
Largemouth bass is a kind of typical predacious fish, and Sugar metabolism ability is weak.It is chilled to make in largemouth bass before 2015
With very wide, but chilled easily cause that food-safety problem, content of beary metal are high, environmental pollution is big and satisfy since source is not traceable
It is disputed on, Zhejiang Province's appearance policy that takes the lead in limits the chilled use in aquaculture.But it thoroughly bans chilled, needs in largemouth bass
The content for reducing its starch is further broken through in terms of feed.
As the breakthrough of twin-screw bulking process after 2015 adds whole use by reducing the usage amount of starch
Perch material cultivation largemouth bass in state is possibly realized, but could be pelletized using twin-screw bulking process there is still a need for higher starch usage amount
It is qualified.If content of starch is lower than 12%, it will cause particle, more powder, the problems such as rate of swimming is low.And 12% starch usage amount
Still largemouth bass liver is caused centainly to damage, causes cultivation late onset rate higher.Thus, how to further decrease largemouth bass
The content of starch of expanded pellet diet becomes one of the direction that Feed Enterprise in recent years is studied.
Summary of the invention
A purpose of the present invention is that providing one kind, formula is scientific and reasonable, low starch, low-powder ratio, few ultralow shallow lake of cracking
The largemouth bass expanded pellet diet of powder.
A purpose of the invention is achieved in that
A kind of largemouth bass expanded pellet diet of ultralow starch, characterized in that comprise the following components in parts by weight: day the same level fish meal 25-
28 parts, 18-30 parts of Rofe fish meal, 5-15 parts of krill meal, 5-9 parts of fermented bean dregs, 3-7 parts of dried porcine saluble, Strong flour 5-9
Part, 1-4 parts of fish molten slurry, adds 1-2 parts of calcium dihydrogen phosphate, 5-8 parts of soyabean lecithin oil, 2-5 parts of soya-bean oil, 2-3 parts of cuttlefish cream leachate
2.5-3.5 parts of 1.5-2.5 parts of state perch vitamin premix, largemouth bass minerals and other premixes, 0.2-0.3 parts of emulsifier.
Super fish meal, day the same level fish meal, Taiwan grade fish meal, Thailand grade fish meal, regular grade fish are divided into fish meal class in industry at present
Five types of powder, design parameter are as follows:
If day the same level fish meal to be changed to the fish meal of other grades in foregoing invention content, should all cover in protection of the invention
In range.
A purpose of the invention can also be solved using following technical measures:
As more specific scheme, 25-28 parts of day the same level fish meal, 18-30 parts of Rofe fish meal, 5-15 parts of krill meal, fermentation

The largemouth bass expanded pellet diet of ultralow starch of the invention can be improved largemouth bass food ration, improve fingerling growth speed
Degree, whole process reduce Micropterus salmonoides using feed and cultivate the proportion of goods damageds, is illustrated below with reference to concrete application case.
The largemouth bass extruding of ultralow starch raises formula one:
28 parts of day the same level fish meal, 24 parts of Rofe fish meal, 12 parts of krill meal, 5 parts of fermented bean dregs, 5 parts of dried porcine saluble, high muscle
6 parts of flour, 2 parts of calcium dihydrogen phosphate, 5 parts of soyabean lecithin oil, 2.8 parts of soya-bean oil, 3 parts of cuttlefish cream leachate, fish molten slurry 2 parts, California
3 parts of 2 parts of perch vitamin premix, Micropterus salmonoides minerals and other premixes, 0.2 part of emulsifier.
It after above-mentioned raw materials are crushed, mixes according to the above ratio, after pulverizing, after adding emulsifier in mixing machine
It can be made into through twin-screw Bulking Machine.The present embodiment mixed feed crude protein content is 52.1%, crude fat content 9.2%.
The largemouth bass extruding of above-mentioned ultralow starch, which raises formula, can be found in following table:
It is control with certain brand Micropterus salmoides compound feed in the market, above-mentioned ultralow starch largemouth bass expanded pellet diet is test group,
30 days by a definite date comparative tests are carried out in indoor water-flowing cultivating system.It is (flat to randomly choose physical strong, the uniform largemouth bass of specification
Equal weight 165 ± 0.04 g), weigh by band water, random to be grouped, every 60 tail of cylinder, 3 repetitions of every group of feed.During test, daily 9:
00 and 18:00 is satiated with food respectively to be fed primary, and each feeding volume, which is subject in test fish 20min, to be eaten up.Largemouth bass fingerling was through 30 days
After cultivation, FCL weighing counts every case residue test fish quantity, calculates survival rate, and each net cage takes 20 tails measurement body long at random
And weight, calculate rate of body weight gain and growth rate.The data finally acquired carry out one-way analysis of variance using SPSS18.0 software, and
Multiple range test is carried out, P < 0.05 is significant difference.Largemouth bass fingerling items growth performance is as shown in the table:
